How-to Select Resistance thermometer?

How-to Select Resistance thermometer ?

  • Select the right one among various RTDs on the basis of temperature range and accuracy requirement.
    • RTDs work best under the temperature range of -200ºC-850ºC.
    • If you need a higher level of accuracy then RTD is better option.
  • RTD’s are commonly used in applications where repeatability and accuracy are important considerations. Properly constructed Platinum RTD’s have very repeatable resistance vs. temperature characteristics over time.
  • RTD can be used where Stability, Sensitivity and Linearity is important parameter.
  • RTD Design selection:
    • Good heat transition between sheath and the temperature probe to permit short response time and high measuring accuracy.
    • RTD designshould withstand the process vibrations.
